Scalable Electrochemical Concrete Fabrication and Closed‐Loop Recycling

Advanced Science, EarlyView.
The electrochemical‐driven recycling strategy establishes a reversible concrete material flow by extracting Ca, Si, Al, and Fe from concrete waste and regenerating functional feedstocks. These reversed products are reassembled into new concrete, which re‐enters service and ultimately returns to waste, enabling a closed‐loop, waste‐origin, and low ...

Scalable Upcycling of Spent Lithium‐Ion Battery Anodic Graphite to Electronic‐Grade Graphene

Advanced Science, EarlyView.
Graphite anodes from spent lithium‐ion batteries are upcycled into electronic‐grade graphene nanoplatelets for highly conductive screen printing inks (> 104 S m−1). Screen‐printed micro‐supercapacitors confirm the utility of the upcycled graphene (1.78 mF/cm2 capacitance for > 10 000 cycles). Life cycle assessment and techno‐economic analysis highlight

Electrolyte‐Dependent Sodium Plating for Anode‐Free Na‐Ion Batteries Studied by Operando Optical Microscopy

Advanced Science, EarlyView.
Anode‐free sodium‐ion batteries are examined using carbonate‐, glyme‐, and localized high‐concentration electrolytes. Distinct sodium plating morphologies are identified by operando optical microscopy, revealing uniform crystalline deposition for glyme‐based systems.

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Addressing Bottlenecks to Achieve High‐Energy Sodium‐Ion Cells Using Tin Anodes

Advanced Energy Materials, EarlyView.
The challenges in coupling high voltage cathode with Sn‐alloying anode or in anode‐free cell, using glyme based electrolytes to realize high energy Na‐ion cells are reported. Surface protection strategy such as SnO coating on Sn or trapping the parasitic species from poisoning the anode, helps improving the cyclability, with ∼100% capacity retention ...
